Effects of differently shaped textures on the tribological properties of static and dynamic pressure thrust bearings and multiobjective optimization

PurposeThe purpose of this study is to evaluate three types of textures designed to enhance the tribological performance of static and dynamic pressure thrust bearings.Design/methodology/approachTo explore the effects of different types of textures on tribological performance, the Reynolds equation is modified using lubrication theory and computational fluid dynamics methods while considering the influence of cavitation and turbulence on the physical field. In addition, the tribological performance is optimized through an improved selection algorithm based on Pareto envelope (PESA).FindingsThe results indicate that textured thrust bearings exhibit superior tribological performance compared to untextured ones. The circular texture outperforms other textures in terms of load-bearing and friction performance, with improvements of approximately 28.8% and 18.9%, respectively. In addition, the triangular texture exhibits the most significant temperature improvement, with a reduction of approximately 1.93%.Originality/valueThe study proposes three types of textures and evaluates the friction performance of thrust bearings by modifying the Reynolds equation. In addition, the optimal texture design is determined using an improved selection algorithm based on PESA.

Effect of composite textured rough surfaces on the lubrication performance of cylindrical roller bearings

PurposeThe purpose of this paper is to study the impact of different types of textures on the friction lubrication performance of cylindrical roller bearings.Design/methodology/approachIn the present study, the composite texture hydrodynamic lubrication model that takes into account the effects of surface roughness is established, and the Reynolds equation for the oil film is numerically solved using the finite difference method. The study investigates the oil film carrying capacity and maximum pressure of bearings under two different arrangements of four composite textures and conducts a comparative analysis of the oil film characteristics under various texture parameters and surface roughness levels.FindingsWhen the roughness of the inner texture surface and the contact surface are equal, the bearing capacity of the composite texture is intermediate between the two textures. The impact trend of surface roughness on fluid dynamic pressure effects varies with the type of composite texture; the internal roughness of the texture affects the micro-hydrodynamic pressure action. Composite textures with different depths exhibit improved bearing capacities; elliptical cylindrical parallel and elliptical hemispherical parallel textures perform better when their area densities are similar, while other types of composite textures show enhanced bearing performance as the ratio of their area densities increases.Originality/valueThis paper contributes to the theoretical investigations and analyses on designing the textured rolling bearings with high lubrication performance.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-02-2024-0050

Surface Texturing and Wettability Modification by Nanosecond Pulse Laser Ablation of Stainless Steels

Laser surface texturing has attracted growing interest, particularly in functional surface modification. Lasers with nanosecond pulse widths and infrared wavelengths are commonly used for metallic surface texturing because of their low cost and potential for fabricating a large range of textures. In this research, a laser with a nanosecond pulse width and infrared wavelength was used for the surface texturing of 316 stainless steels. Standard grooved and near-isotropic surface textures, as well as novel porous texture and feather-like dendrite texture, were fabricated through single-time laser texturing. Water contact angle tests were performed on the post-process surfaces, and they showed wettability changes from superhydrophilic to superhydrophobic according to different types of textures. Discussion on the relationship between water contact angle and surface roughness, groove width/depth ratio, surface carbon and oxygen contents indicated that it is the surface morphology that impacts changes in wettability. The comprehensive formation mechanism of different textures and the wettability control mechanism through different textures have been systematically discussed. For the first time, the three-level (point-line-area) laser surface ablation mechanism has been established. The proposed findings can be used for future laser texturing process designs on metals using lasers with a nanosecond pulse width and an infrared wavelength for various applications including wettability modification.

The Evocation of P. Eluard’s Poetry in F. Poulenc’s Little Cantata “Snowy Evening”

The relevance of the research topic. The topicality of the issues of the cantata “Snowy evening” is due to the terrible events of the full-scale war that is currently going on in Ukraine. Society painfully reacts to the cruel realities of today, and art helps humanity to overcome these problems.
 The purpose of the study. To reveal the peculiarities of the composer’s reading of Paul Eluard’s poetry in the cantata “Snowy evening” by Francis Poulenc, using a complex analysis of the musical work.
 The methodology. Methodological principles are based on historicism, genre-style, intonation-dramaturgical and interpretive types of analysis; in the article we have used the hermeneutic method, which makes it possible to understand the content features of the figurative interpretation of the work.
 The scientific novelty. Cantata “Snowy evening” by F. Poulenc is analyzed for the first time in Ukrainian musicology, as well as features of the evocation of P. Eluard’s poetry in it.
 The practical significance of this study lies in the expansion and deepening of theoretical knowledge about the choral work of Francis Poulenc.
 The results. The small cantata “Snowy evening” is a psychological portrait of a man whose life was cut short by a terrible war. The first part of the work talks about the hero’s disappointment in a cruel life; in the second part, the author condemns the moral beliefs of society to destruction and war; the third part is shown as the final destruction of the inner and surrounding world; and at the end, in the fourth part, death is presented to the listeners as the only hope for salvation. The allegorical nature inherent in Eluard’s poetry provided ample opportunities for subtle interpretation of the images and symbols depicted in the work. With the methods of musical expressiveness, harmony and rhythm, Poulenc vividly depicted the psychological state of man during the war.
 The compositional unity of the literary and musical layers of the cantata is determined by the logic of the evolution of the feelings and emotions of the lyrical hero. Poulenc uses a detailed approach to the verbal text, based on the music-text principle of formography. Music expands the content of poetry, brings it to a new figurative and meaningful level. The composer subordinates the music to the free metric of the poem. The original cantata style combines the stylistic principles of different eras. The composer uses the expressive means of ancient genres and the principles of modern choral writing.
 The search for new harmonic structures and combinations allowed Poulenc to expand the timbral colors of the choir. The author uses different types of texture in the cantata. This tool helps to reveal the author’s message about the inseparability of personal and civic sense of self, the inseparability of the fate of every citizen from the fate of the nation. Despite the numerical structure, the cantata has many common intonation connections that pass through all parts of the cycle and create a unity of plot and space.

PRINCIPLES OF ORCHESTRAL STYLE IN SYMPHONIC FRESCOES “TARAS BULBA” BY SERHIY TURNIEIEV

Statement of the problem. The works of Serhii Petrovich Turnieiev – Honoured Artist, composer, professor – have made a significant contribution to the musical culture of Ukraine. His creativity attracts the attention of musicologists from different generations and needs more extensive study. The novelty of the research. The article makes up for the shortage of scientific works covering the orchestral style of S. Turnieiev in connection with his compositional thinking. The work highlights the leading role of orchestration – an important expressive and logical-constructive tool in the music of the twentieth century – in organizing the artistic integrity of the Symphonic Frescoes “Taras Bulba”. Literature review. The theoretical basis of the article is the work on the study of orchestration and orchestral style (Kars, 1990; Blagodatov, 1963; Shabunova, 2008; Korobetskaya, 2011, Halmrast, 2000; Hundsnes, 2010;. McAdams 2019; Monel, 2012; Otto, 1983; Rakochi, 2020; Urniecius, 2018; Wallmark, 2019). In addition, the paper refers to the articles defining the term “Symphonic frescoes” (Tikha, 2009; Tishchik, 2019; Belova, 2020). The aim of the article is to study Symphonic Frescoes “Taras Bulba” by S. Turnieiev from the standpoint of orchestral style. The article uses analytical, genre, style, historical, structural-functional, comparative, systematic generalization methods of research. Results and conclusions. The orchestration of Symphonic Frescoes “Taras Bulba” by S. Turnieiev is characterized by: 1) a variety of orchestral texture as a supplier of semantics, which gives the orchestration semantic and logical-constructive functions in organizing a large-scale work; 2) a combination of functional and coloristic orchestration; 3) orchestral flavor, sound, picturesqueness; 4) large strokes, avoidance of details, which is motivated by the genre of the work. The orchestration analysis of S. Turnieiev’s large-scale symphonic work “Taras Bulba” made it possible to draw the following conclusions regarding his orchestral style: 1) the composer’s orchestration is determined by the principles of his compositional thinking and aesthetic ideas; 2) the orchestration of the work is influenced by the genre of the work and the individual genre decision; 3) the composer chooses the orchestral ensemble сonsidering the practicality of the performance and the concept of the work; 4) there is an interpenetration of functional and coloristic orchestration in accordance with synthetic composer’s thinking. The composer operates with different types of texture, which has an important form-making and dramatic role, and applies traditional and innovative techniques.

HYBRID TEXTURE IDENTIFICATION METHOD

The importance of the modeling mode in systems of computer visual pattern recognition is shown. The purpose of the mode is to determine the types of textures that are present on the images processed in intelligent diagnostic systems. Images processed in technical diagnostic systems contain texture regions, which can be represented by different types of textures -spectral, statistical and spectral-statistical. Texture identification methods, such as, statistical, spectral, expert, multifractal, which are used to identify and analyze texture images, have been analyzed. To determine texture regions on images that are of a combined spectral-statistical nature, a hybrid texture identification method has been developed which makes it possible to take into account the local characteristics of the texture based on multifractal indicators characterizing the non-stationarity and impulsite of the data and the sign of the spectral texture. The stages of the developed hybrid texture identification method are: preprocessing; formation of the primary features vector; formation of the secondary features vector. The formation of the primary features vector is performed for the selected rectangular fragment of the image, in which the multifractal features and the spectral texture feature are calculated. To reduce the feature space at the stage of formation of the secondary identification vector, the principal component method was used. An experimental study of the developed hybrid texture identification method textures on model images of spectral, statistical, spectral-statistical textures has been carried out. The results of the study showed that the developed method made it possible to increase the probability of correct determination of the region of the combined spectral-statistical texture. The developed identification method was tested on images from Brodatz album of textures and images of wear zones of cutting tools, which are processed in intelligent systems of technical diagnostics. The probability of correctly identifying areas of spectral-statistical texture in the images of wear zones of cutting tools averaged 0.9, which is sufficient for the needs of practice.

Thickness effect on structural properties of post annealed barium hexaferrite films deposited by ion beam sputtering

Barium hexaferrite thin films were prepared by ion beam deposition on sapphire (102) single crystal substrates. The structural properties of the films were analyzed by means of X-ray diffraction, atomic force microscopy, magnetic force microscopy and scanning electron microscopy. The obtained results were interpreted as a presence of layered structure with different types of texture and its formation mechanism is proposed. The significant influence of BaFe12O19 thickness on its microstructure was observed. Films obtained under certain conditions are potentially fit for further growing of oriented hexaferrite with out-of-plane orientation of c-axis.

Using mechanical testing to assess the effect of lower-limb prosthetic socket texturing on longitudinal suspension

To function effectively, a lower limb prosthetic socket must remain securely coupled to the residual limb during walking, running and other activities of daily living; this coupling is referred to as suspension. When this coupling is insufficient longitudinal pistoning of the socket relative to the residual limb occurs. Increasing friction of the socket/liner interface may improve socket suspension and textured sockets may be fabricated relatively easily with 3D printing. The aim of this study was to investigate longitudinal displacement of sockets with different types of textures under two suspension conditions: passive suction and active vacuum. In order to do this, we developed a mock residual limb and mechanical testing protocol. Prosthetic sockets, 14 textured sockets and an Original Squirt-Shape (OSS) Socket, were fabricated from polypropylene copolymer using the Squirt-Shape™ 3D Printer and compared to a smooth socket thermoformed from polypropylene copolymer. Sockets were mounted onto a dual durometer mock residual limb and subjected to four levels of distraction forces (100 N, 250 N, 500 N and 650 N) using a hydraulic material testing system. There was a statistically significant three-way interaction between suspension, force level and texture (p < 0.0005). Longitudinal displacements between textured and reference sockets, for all force levels and both suspension conditions, were significantly different (p < 0.0005). Using these newly developed mechanical testing protocols, it was demonstrated that texturing of polypropylene copolymer sockets fabricated using Squirt-Shape significantly decreased longitudinal displacements compared to a smooth socket. However, none of the novel textured sockets significantly reduced longitudinal displacement compared to the OSS socket under passive suction suspension.

Texture Analysis and Fracture Behavior of Zircaloy-4 Processed Through Swaging

Zirconium alloy (Zircaloy-4) was cold-worked using the swaging process and subsequently subjected to mechanical and microstructural characterization in the present work. The influence of feed rate (0.7, 1.25, 2 m/min) during swaging on phase analysis, tensile properties and fracture behavior of the alloy was investigated. The swaged Zircaloy-4 samples were annealed at 732 °C for 3 h holding time to study the microstructural evolution and changes in its fracture behavior. Tensile test results show the improved tensile strength and ductility in the case of 1.25 m/min feed rate. The three-point bend test was performed on swaged and annealed samples to study the fracture behavior of Zircaloy-4 alloys. The apparent fracture toughness value of swaged samples (76.20 MPa.m0.5 for 0.7 m/min, 69.22 MPa.m0.5 for 1.25 m/min, and 57.52 MPa.m0.5 for 2 m/min) and annealed samples (45.12 MPa.m0.5 for 0.7 m/min, 44.37 MPa.m0.5 for 1.25 m/min and 41.81 MPa.m0.5 for 2 m/min) are reported in this work. The result shows the higher fracture toughness for swaged samples due to higher dislocation density. The deformed and annealed Zircaloy-4 samples were characterized by scanning electron microscopy–electron backscattered diffraction (SEM–EBSD) to elucidate the fracture behavior as well as phase analysis of the alloy. Texture analysis was performed using EBSD on the samples subjected to swaging at different feed rates. It reveals different types of texture on swaged and annealed rod samples. The swaged samples show basal texture 〈0002〉, and annealed samples show combination of basal 〈0002〉 and prismatic $$ \langle 10\bar{1}0\rangle $$. Different types of textures are observed with varying feed rates and are found to be directly correlated with tensile and fracture properties.

Arrangements for bandura of polyphonic work by J.-S. Bach in performing and educational practice: methodological aspect

Methodological approaches to the problem of arrangements of polyphonic material for bandura are presented. The problem of comparative comparison of performance capabilities of Kyiv and Kharkiv banduras, the corresponding ways of playing them when performing a polyphonic texture is raised. Prospects for wider involvement of the Kharkiv bandura in performing and educational practice are considered. The professional training of a modern bandura performer should be focused on overcoming certain stereotypes about the technical capabilities of the instrument. The task is to expand the means of performance, to develop new methods and techniques, and to enrich the original and interpreted repertoire of various epoch-making, national and individual compositional styles. A modern bandura performer must develop his musical thinking, aimed at mastering different types of textures, including atypical for the instrument, samples of different types of polyphonic presentation. The aim of the article is a methodological analysis of arrangements of a number of polyphonic works by J.-S. Bach for bandura, consideration of possibilities and variants of interpretations of polyphonic material for bandura of Kharkiv type. Among the examples it is a comparison of modern bandura teachers’ interpretations of “Short Preludes and Fugues for Organ” by J.-S. Bach. Our author’s versions of the interpretation of these and other polyphonic works by J.-S. Bach for Kharkiv type bandura have been presented in the performance classes at Ternopil Volodymyr Hnatiuk National Pedagogical University and Ternopil Solomia Krushelnytska Vocational Music College The research methodology consists in applying a set of relevant methods: the method of systematic analysis, historical-stylistic method to consider the problem of arrangement, comparative method for comparing the features of transcriptions for Kyiv and Kharkiv bandura, and generalization method to formulate relevant conclusions. There has been introduced the arrangement of the Prelude and Fugue № 13 Fis-Dur from the 1-st volume of DTK J.-S. Bach for a bandura of Kharkiv type with a mechanism (design by V. Gerasymenko), which made it possible to illustrate the technical and expressive possibilities that the performer of the bandura of Kharkiv type gives. Thus, Kharkiv way of playing and the modern construction of the bandura of Kharkiv type by V. Gerasymenko proves its perspective in many aspects concerning arrangement and performance of polyphonic works, show significant potential of technical and expressive possibilities for performing Baroque and Classicism music at a high artistic level and is a powerful stimulus for further development of bandura performance in Ukraine.

Structure guided image completion using texture synthesis and region segmentation

Image completion techniques are often used to fill in damaged images. In this study, a novel method is proposed that can handle large hole regions surrounded by different types of texture. This method is based on reconstructing damaged texture structure and texture synthesizing. The images are segmented into several regions and similar regions touching the hole region are linked, thereby resulting in new regions. It is found that the new regions provide sufficient information to generate a guidance map, which serves as a soft constraint in the inpainting process. With the guidance map, the hole is filled by using a global optimization texture-synthesis method. The experimental results illustrate that this novel method is a potential tool for image completion.

Influence and Application of Texture in the Works of Contemporary Iranian Painters (From 1987 to 2017)

Visual elements are one of the most prominent dimensions of visual arts which through it the broadest and most widely concepts are perceived by various human communities composed of different races and nationalities. Texture is very important as one of the visual elements influencing the artwork, especially painting works due to its visual appearance. Contemporary Iranian painters, like other painters in the world, have used the element of texture and created countless artworks. The authors examine the works of 10 contemporary Iranian painters in this regard. Accordingly, in this research, it is attempted to study the works of these artists by analytical-descriptive method with the aim of influencing the visual element of the texture as well as effectiveness on conveying the expression and meaning to the audience. The results of library and field studies show that the painters used different types of visual elements of textures in their works: actual texture, simulated texture, abstract texture and invented texture. Each of these artists has drawn design with regard to their social, emotional, and intellectual concerns of different types of textures to express their subject matter to the audience better. In fact, these painters have been able to create a remarkable and diverse work in terms of composition and visual features from the texture.

Chondrule radiative cooling in a non-uniform density environment

In an effort to better use thermal histories of chondrules in chondrites to test chondrule formation models, the present note addresses the formation of chondrules through the radiative cooling of a droplet cloud of non-uniform density. More generally, we show that the cooling rates obtained can be related not only to the different types of texture of the chondrules but also to their relative abundance in order to evaluate the relevance of models concerning the formation of chondrules.

Application of Texture Analysis Technique in Formulation Development of Lyophilized Orally Disintegrating Tablets Containing Mannitol, Polyvinylpyrrolidone and Amino Acids.

Orally disintegrating tablets (ODTs) attract a great attention as this easy swallowing dosage form often improves patient compliance. In the current work, orally disintegrating tablets comprising mannitol, polyvinylpyrrolidone (PVP) and an amino acid (alanine, glycine or serine) with various PVP-to-amino acid ratios were formulated. The combination of mannitol and an amino acid was aimed to use the advantages of mannitol, the matrix-supporting and disintegration agent, and to reduce the total amount of sugar/polyol in tablets. Tablets were manufactured by freeze-drying and their properties (appearance, internal structure, disintegration, mechanical and texture properties, moisture uptake, shrinkage, thermal properties) were assessed. In the work, great emphasis was placed on illustrating the applicability of the Texture Analysis of the freeze-dried cakes directly in vials in formulation development. The results show that the appearance, mechanical properties, disintegration and shrinkage of the freeze-dried ODTs depend significantly on the excipient composition with PVP playing the leading role. Partial mannitol replacement with an amino acid has a limited impact on the tablet properties. The presence of an amino acid also has no impact on the PVP-mannitol interaction. The mechanical and texture properties of freeze-dried ODTs depend non-linearly on the PVP content. The transition between the different types of textures occurs in a narrow range of PVP concentrations regardless of the type of amino acid in a formulation. The non-linear effect of PVP on various tablet properties should be taken into account when designing ODT formulations as it can compromise the robustness of the manufacturing process.

Influence of wire-EDM textured conventional tungsten carbide inserts in machining of aerospace materials (Ti–6Al–4V alloy)

ABSTRACTImportance of this present investigation is to identify the influence of modified tool (tool with texturing) on the process of orthogonal turning of Ti–6Al–4V work material. To achieve the enhanced turning conditions, four different types of textures (plain conventional, cross, perpendicularly textured and parallel textured tool to the chip flow direction) were fabricated on the rake face of the tool insert and the lubricant used during the machining process is molybdenum disulfide (MoS2). Machining forces (the force of cutting and feed), angle of shear, chip morphology, temperature distribution between tool and chip were measured. Shear strain and strain rate were also computed and compared with all type of cutting tools. Experimental results revealed that the cross-textured cutting tool exhibit an effective reduction in cutting force, friction, shear strain and strain rate. The favorable metal removal condition of curling chip with low diameter was achieved through cross-textured tool.

Fluid Inclusions and Rare Earth Elements (REE) analysis in calcite veins: Tectonic - diagenesis interaction in the Rosablanca formation, Mesa de los Santos sector, eastern cordillera, Colombia

Studies conducted by means of petrography, cathodoluminescence, SEM, fluid inclusion and REE geochemistry in core samples from the Rosablanca Formation in the Mesa de Los Santos sector, identified two types of material: the host rock classified as Packstones and Grainstones, and veins that texturally expose three types of filling (blocky texture, blocky elongate texture, fibrous texture). Diagenesis is characterized by dissolution, carbonate cement precipitation, compaction, fracturing and fluid circulation through fractures during at least three episodes; these diagenetic processes were contemporaneous with the distensive and compressive tectonic regimes regionally dominant during the Cretaceous, Paleogene and Neogene in the study area. The fluids that generated the different types of texture inside the veins were brines that belonged to the H2O – NaCl – CaCl2 system, with salinities between 0.03 – 12.96 % wt eq NaCl, derived from the Rosablanca Formation that was deposited under oxic conditions, retaining their marine character and implying an autochthonousorigin for the REE present in the veins. The conditions of entrapment for fluid inclusions during the early event were heterogeneous, arising from an immiscible mixture of brines andhydrocarbons, while in the second, they were homogeneous with later post-entrapment processes.later post-entrapment processes.

COMPARATIVE STUDY OF THE OPTICAL PROPERTIES EFFECT OF THE FACADE EXTERIOR COATING ON THE BUILDING ENERGY DEMAND

There are different technologies to optimize the use of solar energy in construction systems, with the aim of improving the building energy efficiency and also to reduce the effect of solar radiation on the exterior coatings, which in turn affects the urban areas warming. Among these technologies, chromogenic devices based on materials whose optical properties can be reversibly modified by some external stimulus have become relevant. These materials are especially interesting because they adapt to variations of solar radiation during the day and throughout the different seasons of the year. The facade coating may have different types of texture or color, which determine specific optical properties. One of these properties is the absorptance, which determines the amount of solar radiation absorbed by the material with respect to the incident radiation. The effect of the absorptance on the building energy demand will be conditioned by other parameters that also influence it, such as the climatic zone, orientation and thermal properties of the wall. In the work presented, the influence of the optical properties of three types of exterior facade coating on the building energy demand is analyzed. The materials chosen for this study are a conventional white Portland cement, a belitic cement synthesized in the laboratory by a process of low energy and low CO2 emissions and a brick representative of a brickwork wall, presenting the first two a more polished finish and clearer colors than the second. The final objective of this study is to determine the parameters that optimize the utilization of the optical properties of the studied coatings in the building energy efficiency.

Glioblastoma and Survival Prediction.

Glioblastoma is a stage IV highly invasive astrocytoma tumor. Its heterogeneous appearance in MRI poses critical challenge in diagnosis, prognosis and survival prediction. This work extracts a total of 1207 different types of texture and other features, tests their significance and prognostic values, and then utilizes the most significant features with Random Forest regression model to perform survival prediction. We use 163 cases from BraTS17 training dataset for evaluation of the proposed model. A 10-fold cross validation offers normalized root mean square error of 30% for the training dataset and the cross validated accuracy of 63%, respectively.

Laser Surface Texturing of Nickel Superalloy to Improve Adhesion Bond Strength of Thermal Barrier Coating

Laser surface texturing was adopted as a strategy to improve the adhesion bond strength of thermal barrier coating generally used in aero turbine components. A picosecond Q-switched Nd: YAG laser operated at 532 nm wavelength was used to perform laser surface texturing. Two different types of texture namely, oriented square pattern having 250 µm width and 250 µm pitch and trapezoidal pattern having 150 µm width and 250 µm pitch were textured on nickel superalloy C-263 surface prior to air plasma spraying of NiCrAlY bond coat. The microstructure and surface morphology of these patterns were characterized by Optical Microscope (OM) and White Light Interferometer (WLI). The presence of pre-defined texture in the laser ablated region and greater surface contact enhanced the mechanical interlocking with the bond coat. The generation of grooves increased the surface roughness of textured substrate 6 times greater than grit blasting. Further, the trapezoidal pattern exhibited higher surface roughness due to greater laser ablated area. The adherence was tested by adhesion bond strength test which showed 35 MPa and 37 MPa adhesive strength for oriented square and trapezoidal pattern, respectively. The fractal analysis showed that the textured substrate failed predominantly by cohesion.

Single-Image Shadow Removal Using 3D Intensity Surface Modeling.

Shadow removal from a single image is a challenging problem, whose solution is proposed in this paper using 3D intensity surface modeling. Due to the high-order textural content in the original images, a direct modeling of the intensity surface of shadow image is difficult. In this paper, image decomposition technology is used as an edge-preserving filter to remove the textural detail while keeping the local-smoothness pattern of image intensity surface. Using 3D modeling, a proper intensity surface of illumination in shadow region can be obtained based on that corresponding to the same texture in the non-shadow one. Thus, the intensity surface of shadow region can be compensated with a respective shadow-removal. Experimental results demonstrate the effectiveness of the proposed approach in the aspect of single-image shadow removal. In contrast to the alternative methods, it is not limited by additional assumptions or conditions; moreover, it can deal with the non-uniform and curved surface shadows, and is applicable to the shadow regions consisting of different types of textures.
